ANIMAL-SHE ARS Specification of Letters Patent.

Patented July 6, 1909.

Application filed September 28, 1908. Serial No. 455,065.

To all whom "it may concern:

Be it known that I, W'ALTER M. CAIIILL, a citizen of the United States, residing at WVinona, in the county of WVinona and State of Minnesota, have invented a new and useful Animal-Shears, of which the following is a specification.

My invention relates to improvements in animal shears and more especially to the class of shears known as clippers and used,

for shearing sheep.

It is a further improvement on the shears covered by my United States patent issued on May 26, 1908, No. 888,867, and another application now pending and of the Serial No. 451,895, filed Sept. 5th, 1908.

The object is to further improve certain parts and provide efficient means for oiling same.

In the drawing: Figure 1 is a top View of an animal shear containing the improved parts embodying my present invention and the collar 28 unscrewed. Fig. 2 is a longitudinal sectional view of Fig. 1 about as on the line a-a and showing the improvements in actual working position.

Referring to the drawing by reference numerals the body portion of the shear comprises a shell 1 with a rearwardly extending tubular portion 2 and a forwardly projecting plate 3.

Upon the front part of the shell 1 is held by screws 5 and 6, a cover 7 which is of such shape that it snugly fits onto the shell 1. The front part of said cover has a head 8 in which is journaled the upper end of a vertical rock shaft 9 the lower end of which rests in a cavity 10. The head 8 has outside screw threads 8 adapted to receive an internally threaded cap 11 having an oil hole 12 in its top to oil the shaft. The means holding said cap in adjusted position upon the end of the shaft and many other particulars are not herein set forth since they are described and claimed in my former patent and application above referred to. Said rock shaft has secured to it a bifurcated vibrator arm 13 in which operates a spheric roller 16 carried by the pin 16 of a crank 17 of a driven shaft 15. Another arm 13* extends from the vibrator shaft and operates a shear blade 35 upon a comb plate 36 fixed to plate 3 by screws 20. Rearwardly of the crank 17 the shaft 15 is journaled in a web 21 of the shell 1. The rear end of the cover 7 rests against the web at 22 and the line 23 indicates where the cover rests on or against shell 1.

As already mentioned, the portion 2 is tubular. It is also screw threaded at 2 1- and just forward of the web, and this scrcw threaded portion, the shell 1 and cover 7, are also tubular and cone-shaped at 25; and upon said cone fits the funnel shaped front end of a sleeve 27, which has a cylimlrical rear portion threaded upon the threads 24' and provided with an oil hole 28 adapted to register with an oil hole 29 in the tube 2 when the sleeve is screwed partly rearward for purpose of oiling the shaft 15 by filling the tube 2 and the handle 2 extending therefrom, as partly shown in dotted line in Fig. 2, and which in its rear end has a bearing (not shown) for the shaft 15 and to close the end of the handle. When the sleeve or collar 27 is screwed fully forward the hole 28 passes forward of the hole 29 and the latter is closed by the solid part of the sleeve, and. the funnelshaped portion 26 of the sleeve holds the rear end of the cover 7 firmly.

WVhat I claim is 1. In animal shears of the kind described the combination of a frame, a hollow, bottomed handle extending therefrom and liaving its ends closed so as to hold lubricating oil, a driven shaft extending longitudinall; through said handle, being journaled in its bottom and having at its front end a crank, and a shear blade having operative connection with the crank, said handle having near its front end an externally screw threaded portion with an oil hole through it, a sleeve or collar threaded upon said portion and having an oil hole adapted to register with the oil hole in the handle when the sleeve is in a rearward position but not when it is in a forward position.

2. In animal shears of the kind described the combination of a frame, a hollow, bottomed handle extending therefrom and having its ends closed so as to hold lubricating oil, a driven shaft extending lmigitudinally through said handle, being journalcd in its bottom and having at its front end a crank, and a shear blade having operative connection with the crank, said handle having 11 an its front end an externally screw threaded portion with an oil hole through it, a sleeve or collar threaded upon said portion and having an oil hole adapted to register with the oil hole in the handle when the sleeve is in a llO rearward position but not when it is in a for- 1 frame and a sleeve ring or collar screw ward position, said sleeve being funnelshaped in its front end and the frame being hollow and provided with a cover both of which have their rear ends formed into a single conic portion upon which the funnel fits when the sleeve is in its forward position and screws for holding the front end of said cover to the frame.

3. An animal shear having a hollow frame with a handle extending rearwardly therefrom and a cover upon the frame, screws holding the front end of the cover to the threaded upon the front part of the handle and having at its front end a funnel shaped portion by which to hold the rear end of the cover to the frame, the adjacent portion of the frame and its cover being tapered so as to fit in the funnel.

In testimony whereof I afiiX my signature, in presence of two witnesses.
